05' Ec300 Cdi
 

I've heard some of the late model 05' EC300's come with a dual mapped CDI but no toggle switch. How can I tell which one I have. My CDI is located under the seat up under the gas tank where it meets the seat and air box. Not sure if this is the same location for all models? thx/Mike

Dual mapped were mounted to rear fender. But anything is possible with GasGas.

I have the 05 MC250 . I heard they ran out of the standard dual map Kokusan CDI late 05 and stuck something else in there. My CDI is under the tank and the dual map is mounted to the fender. I don't know about other bikes.

I don't know what I have, but I don't think my bike delivers power anything like an MX bike, more like a trials bike

hi m8,cdi unit should be under your seat.
flick the cdi unit out of the rubber strap and underneath you should,hopefully,find 2 wires,one orange and one black.
these will be joined or separated.
if you have these,all you need is the handlebar toggle switch and,hey presto,dual ignition mapping.

What if you don't want the toggle switch? Could I simply "jump" the circuit to get it to switch over? Or perhaps snip one of the wires to leave it permanently in the "sunny" or haul azz setting? I weigh 220 and need more. Quite a bit more off the bottom.

Sure. How did you make out with the jetting and reed spacer?

I spent the evening loading up the truck and the camper. Decided to leave earlier and work on the bike tomorrow afternoon after I get set up. In other words, when there will be no phone or wife or kid distracting me.:D

I am really hoping the jetting is whack. That way it will be easy and give me hope.

I should be able to report on the spacer removal and to what I have in it as far as jets and needles on Sunday. My buddy is bringing a bunch of jets and needles for us to play with on Saturday. I do know that the needle is not the LTR needle. So that gives me hope right there. I will be ordering an LTR kit tomorrow on my way North to the woods...

You should see significant improvements. No need for a reed spacer on a 250, they dropped that on the '07s. The '07 motor is close to the '06 and my bike just plain rips, no complaints! Check the condition of the reeds while your in there, VForce reed petals are good for a season, not a lot more.

Let me know how you make out, if your still not satisfied there are other things to do.

I had a good conversation today with a dealer and they said not to run the CDI switch in the sunny mode unless you find yourself using the clutch quite a bit. And for sure don't have it in the "Sunny" mode if you are in deep sand as you are already "Racing" the engine really hard.

When you flip the switch from one setting to the next there is a difference of about 10 degrees in the timing. So that being said, running the switch in the "Sunny" mode will lean the motor a bit and if you run your bike like this there could be slight damage.

Are you sure? Ten degrees seems rather extreme! :eek: Thats like rotating the stator plate approx 10mm clockwise, if the slots would allow it. Of course that would be a static timing advance but you get the idea. I would have thought maybe 1 - 2 degrees at certain RPM by the way it feels. On the 250 it really doesn't feel like a big difference, noticable but not that significant. I think that sloppy jetting could eaisly mask any difference you may feel from the CDI on the 250. 300 may be another story.
